WHISK.

Application filed April 30, 1924. Serial No. 709,962.

Be it known that I, STEPHEN Gr. VILsoN,

a citizen of the United States, residing at Philadelphia, county ottPhiladelphia, State ot' Pennsylvania, have invented a new and usefullVhisk, of which the following is a specification.

In whisks as heretoforemamifactured, the whisks are thrown away when thestraws are worn out. In whisks oi' the better grade, an ornamentalhandle is employed and in many cases an ornamental shield is'providedwhich surrounds the head oi" the whisk.

One of the main objects oi my present invention is to devise a novelwhisk wherein when the straws are worn out the whisk can be replaced bya new vone and the handle locking mechanism and shield can be usedagain.

lWith the above and other objects in view which will hereinafter appear,my invention comprehends a novel construction oi' a whisk.

It further comprehends a novel construction of a dowel stick and novellocking mechanism to secure the handle on the dowel stick so that thehandle can be removed when desired.

Other novel `features of construction and advantage will hereinaftermore clearly appear in. the detailed description and the appendedclaims.

For the purpose oi' illustrating the invention, I have shown in theaccompanying drawing a typical embodiment of it, which, in practice,will give'reliable and satisfactoryT results. It is however to heunderstood that this enlbodiment is typical only and that the variousinstrumentalities of which my invention consists can be variouslyarranged and organizi-id, and that the invention is not limited to theprecise arrangement and organization of these instrunieutalities asherein set forth.

Figure 7 represents a vertical section of the whisk.

Figure 8 represents, in front elevation, and indetached position, thedowel stick.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings:

1 designates a whisk embodyingmy invention. 2 is the dowel stick towhich are connected the inner or corner straws 3 by means of the wire t,and, in a similar manner, the outer straws 5 are connected to the dowelstick by the wire 6.

The dowel stick has a tapered slot, the side walls of which convergetowards and open through the upper end of the dowel stick. 8 is anaperture opening into the slot 7. 10 designates the grasping handlewhich is apertured as at 11 to receive the dowel stick. The walls of theaperture 11 near the top are tapered or converge towards the upper endof the handle as at 12 forming an opening through the top of lesserdiameter, and the handle portion surrounding the upper end of theaperture 11 is recessed as at 18 to receive a plate or washerl/i.Extending ontwardly from about the center of the plate 14 as at 15 is aslot 16. i

The handle 10 is secured to the dowel stick by means of novel lockingmechanism which lwill now describe.l y

17 designates la key having in its grasping 'portion one or moreapertures 18 toenable one to hang the whisk on a nail or other support.The head 19 of the key is split longitudinally as at 2O and oppositeedges 21 converge or taper upwardly. The inner end of the head is ofreduced diameter as at 22 in order to enter the aperture, 8 in the dowelstick. The head is provided with an anchor or head 23 which has anaperture 2li through it which is preferably rectangular. 25 designates aspring having its inner end offset as at 26, and its outer end is ofreduced diameter as at 27. The spring passes through the aperture 24 sothat opposite edges engage the tapered diverglng walls 28, and theportion 26 overhangs the head portion 22. The head above the anchor iscut out at opposite sides as at 29.

The -parts when assembled' appear' as in Figure 7. The shield 9 isplaced in position on the head of the whisk and the handle. 10 is placedon the dowel stick 2. Thel lock ing mechanism as shown in Figure 2 isthen inserted into the narrow part of the slot- 7-in the dowel stick.The key is then given a quarter turn to bring the parts into theposition seen in Figure 7. The tapered sides 21 engage'the tapered wallsof the slot 7. The lower end of the locking spring is in the aperture 8in the dowel stick and the locking end 27 moves outwardly in the slot 16into the position seen in Figure 3. The key has the recesses 30, so thatwhen the key is turned in the slot 1G, it locks with the plate lll asshown in Figure. 7. lit will A be apparent that when the spring is inthe position seen in Figure 8 the key cannot be turned, and the springmust be pressed inwardly before the key can be moved into its unlockedposition and withdrawn.

The dowel sticks are usually made of wood and the slots vary a little insize when manufactured. For this reason I provide the taper l2, so thatwhen the handle is being locked in position, the upper end of the dowelstick will be compressed to a desired degree and the tapered walls ofthe key head will 'always engage the tapered walls of the slot in thedowel stick as the closing action of the dowel stcik will be more rapidthan the downward movement of the key.

Then the locking portion or spring QT of the key is pressed inwardly,the key can l be turned and with the spring and pla withdrawn from thedowel stick. The hair die and shield can then be removed to renew thewornout whisk.

The width of the spring is slightly less than the length of the slot 16in the plate l Then the spring is passed through the opening in the keyhead it overlaps the hefi on both sides and prevents the twisting of theparts of the shank when the key is turned into locking position. iis thekey is turned into its locking position the sharp points of the anchorportion will be imbedded into the wood of the walls of the tapered slotof the dowel stick. The spring resting against the opposite slantingedges of the; walls of the aperture in thehead prevents the head fromdrawing together and retains the key in. the spread position into whichit has been set so that the proper fit will. be obtained with the wallsof the tapered slot of the dowel stick.

It will be apparent that when the key is withdrawn the plate will bewithdrawn with it. After thesprng plate and key have been assembledtogether they remain to getlier as a unit of structure and are in.-sertible into assembled position and renier'- able from assembledposition as a unit of structure,

The funetipn ai'4 theesletf. in tra head er the key is to enable one tospread the head or bring it together so that the proper lit will beobtained with the variations of ttapered slot in the dowel stick. When.the key is spread to fit the slot in the dowel etui it will be apparentthat the spring bears against the tapered walls in the aperture of thehead and will retain the key in the spread position to which it has beenset.

It will now be apparent that I have devised a new and useful whisk whichembodies the features of advantage enumerated as desirable in thestatement of the inven-A tion and the above description, and while lhave, in the present instance, shown and described a preferredembodiment thereof which will give in practice satisfactory and reliableresults, it is to be understood that this embodiment is susceptible ofmodification in various particulars without departing from the spirit orscope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:
